PETER RENEY CAMPBELL, OF BRIERFIELD, MISSISSIPPI.

CLUB-CUTTER.

SPECIFICATION forming part of Letters Patent No. 595,117, dated December 7, 1897.

Application filed December 10, 1896. Serial No. 615,080. (No model.)

To aZZ whont it may concern.-

Be it known that I, PETER RENEY CAMP- BELL, of Brierfield, in the county of Warren and State of Mississippi, have invented a new and Improved Cultivator, of which the following is a full, clear, and exact description.

The purpose of thisinvention is to provide a superior cultivating apparatus of that class in which the clods are broken by knives or blades held to run along the ground; and the invention employs a knife-frame carrying longitudinal blades and plowshares rearward of the blades to throw the earth inward as the machine passes along the ground.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the main por tion of the elod-cutter, the uprights from the runners being in horizontal section. Fig. 2 is a longitudinal vertical section through the clod-cutter. Fig. 3 is a transverse section through the machine, and Fig. 4 is a detail sectional view illustrating the manner in which the saw-cutters may be dropped to extend below the runners of the machine.

The main frame of the machine consists of two runners A, the forward ends whereof are upwardly inclined or beveled as shown in Fig. 2. The two runners are connected by forward and rear bracing-frames B and 3, each bracing-frame consisting of standards 10, projected upward from the runners and connected by cross-bars 11, the standards 10 extending above the said cross-bars. The standards of each bracing-frame, together with the cross-bars, are strengthened by correspondingly-fornied metal plates 12 in order to prevent the main frame from spreading and to impart sufficient rigidity thereto.

A vertical slot or slideway 13 is made in the upper face of each upright of each bracing-frame l3 and B, and these channels or slideways 13 are continued in the inner faces of the runners and the bottom thereof, as shown in Fig. 111 the bottom portions of the slideways 13 of the forward brace-frame and forward portion of the runners blocks are located, while longer blocks 14 are placed in like position in the rear slideways 13, as shown in dotted lines in Fig. 2. These bear ing-blocks 14 and 15 are removably attached to the main frame of the machine by means of screws 16 or their equivalents, as illustrated in Fig. 3, and wear-plates 17 are secured on the bottom portion of the runners to add to the lifetime thereof. A handle 18 is made to extend from side to side of the rear portion of the main frame in order that the machine may be readily lifted and turned, and cross-braces 19 are likewise attached to the rear portion of the runners of the main frame and to the cross-bar of the rear bracing frame.

The main frame is adapted to carry a cutter-frame O, and this cutter-frame is made up of front and rear cross-bars 20, preferably connected by side bar. 21 and braced by diagonal top bars 22. Upon the upper face of this cutter-frame, near the rear, a platform 23 is constructed, upon which the driver may stand or' upon which weights may be placed, and a seat 2% is usually erected upon this platform for the accommodation of the driver, since the machineis adapted'to be drawn by horses or similarly-applied power.

Trunnions 25 are formed at the front and rear side portions of the cutter-frame, and these trunnions are entered and slide loosely in the slideways or channels 13 in the uprights of the bracing-frames and in the runners A, the forward trunnions resting upon the shorter forward blocks 15 and the rear trunnions hearing against the longer rear blocks 1%.

It will be observed, especially by reference to Fig. 2, that the cutter-frame has a downward and a forward inclination.

Slots are made transversely in the bottom surfaces of the transverse bars 20 of the cutter-frame, and in longitudinally-alining slots in the frame sawcutters 26 are entered. These cutters are shaped substantially as a handsaw and have teeth corresponding to the teeth of a crosscut-saw, the teeth extending from the heel of the cutter to the front upper portion of the same, as is also shown in Fig. 2. These saw-cutters are removable from the frame 0, and to that end rods 27 are passed through openings in the said cutters near the top, the rods being also passed in the front faces of the cross-bars of the frame, so that by withdrawing the rods 27 any one or all of the cutters may be removed, if desired.

The rear end of the cutter-frame may be raised and lowered through the medium of a link 30, attached to the central portion of the rear cross-bar of the cutter-frame, and the said link is attached to a lever 31, fulcrumed, preferably, upon the rear bracing-frame B immediately back of the drivers seat, and the lever is provided with the ordinary thumblatch to engage with a rack 32 or other form of keeper.

Shares 34 are removably placed at the rear ends of the runners and in engagement with their inner faces, and these shares are attached by bolts or otherwise to blocks 35 or like rests, as illustrated in Figs. 1 and 2.

Then it is desired to raise the cutters-as, for example, in coming to .or going from a field-the rear portions of the runners are likewise elevated, and this may be accomplished through the medium of drags 36, one of which, in the nature of a bar, is pivoted by means of bolts 37 or like devices at each side of the main frame near the center, the rear ends of the said drag-bars,which are free, being beveled. These drag-bars when not required for use are held horizontally along the sides of the frame free from the ground by passing pins 38 through the said bars and into apertures 39, made in the runners, and when the back of the main frame and the .cutters are to be elevated, as illustrated in dotted lines in Fig. 2, the free ends of the drag-bars are permitted to drop and extend at an angle to the main frame at the sides, the pins 38 being passed through the apertures in the drag-bars and into apertures 40, made in the main frame near the bottom edges of the cutters.

When the shares 34 are attached to the machine, the machine is used for pulverizing ground which is to be planted in rows, the shares serving to throw the pulverized earth in direction of the center of the machine, and it is evident that the clods will be confined to the space between the runners and will therefore be compelled to receive the saw-cutters. The saw-cutters travel through a clod, no matter how hard it may be, with much greater rapidity and with the expenditure of much less power than a cutter having simply a knife-edge, andit will be understood that the saw-cutters will be placed at regular intervals apart or the intervals may be varied, as deemed best.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a clod-cutter or like machine, runners, saw-cutters located between the said runners, and shares placed adjacent to the said runners and back of the said saw-cutters, as and for the purpose set forth.

2. A clod-cutter consisting of runners, cutters longitudinally suspended between the runners, and removable shares having their moldboards facing inward and located at the inner sides of the runners at the rear of the cutters, as and for the purpose set forth.

3. In a clod-cutter or like machine, the combination, with runners, an adjustable frame carried between the said runners, cuttingblades located in the said frame, extending substantially parallel with the runners, and removable bearings for the said frame, as and for the purpose specified.

4. In a clod-cutter or like machine, the combination, with runners, a frame suspended between the runners, cutting-blades removably supported in the said frame, said cutting-blades being provided with saw-teeth, and the blades being in series substantially parallel with the runners, drag-bars pivotally attached to the runners, and locking devices for the said drag-bars, as and for the purpose set forth.

5. In a clod-cutter or like machine, the combination, with runners, slideways produced verticallyin the said runners, bearing-blocks removably placed in the said slideways, and shares removably connected with the inner faces of the runners at their rear, of a frame having movement in the slideways of the runners, cutters carried by the said frame,

and a device, substantially as described, for

raising and lowering the cutter-frame, as set forth.

6. The combination with a frame of vertically-movable cutters extending longitudinally with the frame, and two plowshares carried by the frame and throwing furrows inward toward each other, substantially as described.

7. The combination of two runners having means for rigidly connecting them, a series of cutting-blades extending longitudinally between the runners and movable vertically, and a plowshare carried by the rear portion of each runner, the plowshares facing each other and serving to throw the furrows inward, substantially as described.

8. The combination with a frame, of a series of longitudinally-extending connectingblades having saw-teeth, the blades running parallel with each other and capable of being raised and lowered to engage and disengage the ground, substantially as described.

9. The combination with a frame having two runners and standards rising from the runners, the standards having their adjacent faces grooved, and a cutter-frame having portions respectively projecting into the grooves of the standards and movable vertically between the same, substantially as described.
